Purpose: The purpose of this study was to test the psychometric properties of the 49-item Diabetes Time Management Questionnaire (DTMQ) in individuals with diabetes. The DTMQ was designed to assess general time management skills and those specifically relevant to compliance to a diabetes healthcare regimen.
Methods: Participants completed the DTMQ; the Habits, Attitudes, and Knowledge Questionnaire of Diabetic Compliance (HAK); and the Diabetes Knowledge Schedule (DKS) to provide two indices of construct validity of the DTMQ. Three HAK items related to time management skills (HAK-TM) provided an index of concurrent criterion-related validity for the DTMQ.
Results: Test-retest stability reliability results were significant for DTMQ total and individual item scores. Concurrent criterion-related validity of the DTMQ was supported by a significant correlation with the HAK-TM items. Construct validity of the DTMQ was partly supported by significant correlations with the DKS and two HAK items measuring diet and exercise compliance.
Conclusions: The results support the use of the DTMQ to assess the time management skills of individuals with diabetes.
